Thanks again vgersh99.. I was able to get this working. But encountered in an awk error on some files

awk: Input line 06/15/2009 05:08:18. cannot be longer than 3,000 bytes.

Alternately, I tried accomplishing this using shell script

CNT=` cat $j | grep -i $i | sed 's/'$i'/&\n/g' | grep -wi $i | wc -l `

instead of

CNT=` awk -v pat=${i} '{cnt+=gsub(pat,"&")}END {print cnt}' $j `

That seemed to work on linux, but does not on HP-UX

Any ideas what I need to change to get it working in HP-UX

NAME
grep - search a file for lines containing a given pattern SYNOPSIS
grep [-elnsv] pattern [file] ... OPTIONS
-e -e pattern is the same as pattern -c Print a count of lines matched -i Ignore case -l Print file names, no lines -n Print line numbers -s Status only, no printed output -v Select lines that do not match EXAMPLES
grep mouse file # Find lines in file containing mouse grep [0-9] file # Print lines containing a digit DESCRIPTION
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1 occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is returned. SEE ALSO
cgrep(1), fgrep(1), sed(1), awk(9). GREP(1)
